The Newspapers aren't supposedly handed down by God and considered by its readers to be flawless. The Gospels were originally written in Greek, translated by hand into Latin, and then only after the start of Protestantism did it start to be translated into local languages. That means for the English translation most people read was based on 1500 years of potential mistranslations and transcription errors. It's like playing the "phone game" over 1500 years and expecting the words to still mean something.
Also, to start, Mark and Luke were not disciples or direct witnesses. Their Gospels are just hearsay handed down a generation or two later. John's gospel is the most dramatically different he writes as if he was a witness but there is some doubt that was the case. Matthew supposedly was a direct witness but if he actually was literate (which wasn't all that common back then) he probably would have written in Aramaic - which means yet another level of translation.
Then you have all the Gnostic Gospels that the church decided didn't properly suit their purposes and did their best to destroy and exterminate anybody who preached from them. Same goes for the Apocrypha.
Over half of the rest of the new testament is the writings of the Apostle Paul (some of which have been historically validated). Paul was a PR machine. He was a prolific writer and marketer for the version of Christianity he was selling. His teachings, however, are dramatically different from the teachings of Jesus and he is the main reason the Christian church has drifted so far from what the original message of Jesus was.
